Closure for containers



May 24, 1932. H. s. BRADY ETAL CLOSURE FOR CONTAINERS] Filed Dec. 29,1928 q Patented May 24, 1932 UNITED STATES PATENT OFFICE HUGH S. BRADYAND JOHN J. WILLIAMS, 0F WHEELING, WEST VIRGINIA, ASSIGNORS TOHAZEL-ATLAS GLASS (10., OF WHEELING, WEST VIRGINIA, A CORPORATION OFWEST VIRGINIA CLOSURE FOR CONTAINERS Application filed December 29,1928, Serial No. 329,159.

\ The cap described herein is made, as usual, of ordinary sheet tin,which is rigid and strong; is of the side-seal type; and is used uponcontainers either -with or without a finish.

One of the advantages of the cap resides in the provision ofmeans totake care of any excess rubber of the gasket, resulting fromirregularities in the container.

Another advantage of the cap resides in the particulararrangement bywhich suitable places are provided about the cap for the application ofa cap removing tool.

Another advantage of the cap resides in the provision, in a cap of thistype, of centering and guiding tabs.

1 Other objects of the invention consist in providing a cap'which isinexpensive in manufaeture, highly eificient in operation on containerseither with or without a finish, which is easily applied to a containerand is not deformed, and which is easily removed and Withoutdeformation, so that it possesses a reseal value.

Other objects and advantages of the cap will be apparent to thoseskilled in the art.

For a complete description of the cap, reference is to be had to theaccompanying drawings; in which Figure 1 is a perspective view of acontainer with the cap applied thereto.

Figure 2 is a side elevational view of the cap and container.

Figure 3 is a transverse vertical sectional view of the cap. v Figure4.- is a fragmentary sectional view of the cap applied to a containerwithout a finish, such as a tumbler; and

Figure 5 is a view similar to Figure 4, but showing the cap applied to acontainer having a finish of any usual form.

As stated hereinbefore, the cap is made of sheet tin which is rigid andstrong; and

the cap includes the usual top 1 having an annular groove 2 at theperiphery thereof, and a rectangular gasket 3 having its upper endseated in the groove. The structure thus far described is old and wellknown. But in accordance with the present invention, this ordinarygroove 2 is of considerably greater width than the initial thickness ofthe gasket. Also, an annular flange 4 depends from the periphery of thegroove 2, and this flange terminates with an inturned horizontal flange5, from which inturned flange depends the skirt proper, as indicated bynumeral 6. By reference to Fig. 3, it will be noted that thisconstruction provides a pocket 7, which extends from the inturned flange5 to the top of the groove 2, and which is adapted to receive, when thecap is applied to a container, any excess rubber of the gasket resultingfrom irregularities in the container. The provision of this pocketconstitutes a distinct improvement.

,The skirt 6 terminates with a downwardly and inwardly inclined flange8, which serves tointerlock the cap and gasket; and it will beunderstood, of course, that the pocket 7 also serves as an interlockingmeans to some extent, thoughits primary purpose is to take care ofexcess rubber resulting from irregularities in the container. Aplurality of guide tabs 9 depend from the inclined flange 8. The numberof the guide tabs employ-ed is,-of course, merely a matter of choice.These tabs have no other function than to center and guide the caps ontothe containers, and therefore the tabs may be inclined outwardly, orthey may be Vertical as illustrated in the drawings. Inasmuch as thesetabs center and guide the cap, it is desirable that the tabs should havesome resiliency; we therefore These cut-out portions between the guidetabs constitute a material improvement, in that they provide suitableplaces for the application of a cap removing tool. It is well known,

of course, that considerable diiiiculty is usual ly encountered in theremoval of vacuum caps, and one of the difiiculties is that such capsare so constructed that a cap removing tool cannot be easily applied. Inthe present construction the skirt is spaced from the container by thesealing gasket, and by providing these cutout portions a hook or otherdevice can be engaged under the skirt and the cap can thus be pulled offeasily.

From the foregoing description it.will be apparent that the capdisclosed herein pre sents numerous advantages, 1 The cap is easilyapplied; no deformation is necessary; it is easily removed; and isinexpensive in manufacture and highly ciiicicnt in operation.

It will be understood, of course, that the cap is subject tomodifications in various respects, without. departing from the spirit ofthe invention, and it is intended that all such modifications beincluded within the scope of the appended claims.

lVhat we claim is:

1. A receptacle closure made of tin and including a top and a dependingskirt, a gasket arranged in the skirt, a pocketextending around the topat its periphery and of substantially greater width than the thicknessof the gasket, a pocket extending around the skirt at the top thereofand communicating with the first-mentioned pocket, said pockets adaptedto receive any excess rubber of the gasket resulting from irregularitiesin the container.

2. A receptacle closure made of tin and including a top and a dependingskirt, a gasket arranged in the skirt, a pocket extending around the topat its periphery and of substantially greater width than the thicknessof the gasket, a pocket extending around the skirt at the top thereofand communicating with the first-mentioned pocket, said pockets adaptedto receive any excess rubber of the gasket resulting trom irregularitiesin the container, centerin and guiding tabs extending downward y fromthe skirt, and cut-out portions between the tabs for the application ofa removing tool.

3. A receptacle closure including a top and a depending skirt, a gasketadapted to be arranged in the skirt, a pocket extending around the skirtat the top thereof and adapted to receive any excess rubber of thegasket due toirregularities in the container, centering and uiding tabsextending downwardly from tiie skirt, andcut-out portions between thetabs for the application of a removing tool.

4. A receptacle closure including a top and a depending skirt, a gasketadapted to be arranged in the skirt, a pocket extending around the skirtat the top thereof and adapted to receive any excess rubber of thegasket due to irregularities in the container, center ing and guidingtabs depending from the skirt, said tabs having cut-out portions toincrease the resiliency thereof.

5. In combination with a receptacle, a 010- sure including a top and adepending skirt, a gasket arranged between the skirt and the receptacle,the lower ed e of the gasket being substantially flush with the loweredge of the skirt, inturned flanges as intervals about the lower edge ofthe skirt and projecting slightly beneath the gasket, and centering andguiding tabs also at intervals about the lower edge of the skirt andprojecting downwardly therefrom.

6. In combination with a receptacle, :1. closure including a top and adepending skirt, a gasket arranged between the skirt and the receptacle,a pocket-extending around the top at its periphery and of substantiallygreater width, than the thickness of the gasket, a pocket-extendingaround the skirt and at the top thereof and communicating with thefirstmentioned pocket, said pockets adapted to receive any excess rubberof the gasket resulting from irregularities in the receptacle, the loweredge of the gasket being substantially flush with the lower edge of theskirt, inturned flanges at intervals about the lower edge of the skirtand projecting slightly beneath the gasket, and centering and guidingtabs also at intervals about the lower edge of the skirt and projectingdownward therefrom. r

7. A receptacle closure including a top provided with a pocket extendingaround its periphery, a skirt depending from said to a gasket adapted tobe arranged in the srirt with its upper edge positioned in said pocket,the lower edge of the gasket being substantially flush with the lower ede of the skirt, and centering and guiding ta hs at intervals about thelower edge of the skirt and projecting downwardly therefrom.
